Good properties of Cu₂O nanopowder:

Excellent semiconductor material, good catalytic activity, strong adsorption, bactericidal activity, low temperature paramagnetic.

Application of Cuprous Oxide (Cu₂O) Nanopowder:

1. Catalytic activity: Nano Cu2O is used for photolysis of water, treatment of organic pollutants with good performance.
2. Antibacterial activity. Nano cuprous oxide can interfere with the biochemical reactions of microorganisms, thereby interfering with their physiological activities and even inducing their apoptosis. In addition, due to its strong adsorption, it can be adsorbed on the bacterial cell wall and destroy cell wall and cell membrane, causing the bacteria to die.
3. Coatings: Nano cuprous oxide is commonly used in the coating industry as a marine antifouling primer to prevent marine organisms from adhering to the bottom of the ship.
4. Fiber, plastic: Cu2O nanopowders play an excellent sterilization and anti-mold function in the field.
5. Agriculture field: Cu2O nanopowder can used for fungicides, high-efficiency insecticides.
6. Conductive ink: low cost, low resistance, adjustable viscosity, easy to spray and other characteristics
7. Gas sensor: extremely high sensitivity and accuracy.
8. Fluorescence properties: due to the small particle size, low band gap energy, Cu2O nanopowder can be actived by visible light, and then it can radiate photons to a lower energy level transition, with blue fluorescence activity.
9. Others: nano Cu2O is used for deodorant, flame-retardant and smoke suppressant, barretter, harmful gas removal, colored solution decolorization, etc..
